Parameters

Is the number of characters not to exceed when inserting str. If n is less than 1, the entire string is inserted.

y

Is the y (row) coordinate of the starting position of the string.

x

Is the x (column) coordinate of the starting position of the string.

win

Is a pointer to the window in which the string is to be inserted.

Description

The insstr() function inserts str at the current cursor position of
the stdscr window. The winsstr() function performs the identical action, but in
window win. The mvinsstr() and mvwinsstr() functions insert the character
string at the starting position indicated by the x (column) and
y (row) parameters (the former to the stdscr window; the latter
to window win).

The insnstr(), winsnstr(), mvinsnstr(), and mvwinsnstr() functions insert n characters to
the window or as many as will fit on the line.
If n is less than 1, the entire string is inserted or as
much of it as fits on the line. The former
two functions place the string at the current cursor position; the
latter two commands use the position specified by the x and y
parameters.

All characters to the right of inserted characters are moved to the
right. Characters that don't fit on the current line are discarded.
The cursor is left at the point of insertion.

If a character in str is a newline, carriage return, backspace, or
tab, the cursor is moved appropriately. The cursor is moved
to the next tab stop for each tab character (by default, tabs
are eight characters apart). If the character is a control character other
than those previously mentioned, the character is inserted using ^x notation, where x
is a printable character. clrtoeol(3XCURSES) is automatically done before a newline.
